I am not sure if this is exactly what you are looking for. But an alternative would be to use http://openbuildservice.org/ and just focus on adding solus support to it. It has some nice review features. can check it out in action at http://build.opensuse.org I know its not lightweight and might not follow solus-project vision.

@ikey Ah no, I was talking about git repos.

@JoshStrobl just to clarify, are we both talking about binary repos?

Provide a mechanism for users to browse the repositories, in detail, online
